Yet the same regulator is still on the truck.

That is actually a scary thought but easy to figure.
Consider this : Lead shakes down into the bottom and starts
building a small hill of conduction metal. This then reaches
upward and shorts out plates. Or almost shorts. High current occurs
only in the battery - likely between plates or cells. High current
and hydrogen and oxygen is generated. It likely didn't explode just
pressured and exploded. The gas might have detonated post explode
from sparks being produced.

A) I agree with the those suggesting an ammeter in the ground leg.
THIS IS WITH THE CAR OFF.
You may see 40-50 mA. with doors closed, etc. [Make sure there's no
underhood light.] If it's more, pull fuses one at a time. There may well
be multiple fuse boxes, by the way.
I'm going through this with a friend's car. Despite a new battery
[several actually; the battery people have tried ....] and a 40mA draw,
his keeps dying. I think his issue is he drives his car once every two
weeks, and then not very far. I have a Harbour Fright battery cutoff and
$10 bolt-in charger for him.
B) To check the charging, don't worry about amps. Start the car, measure
the battery voltage at fast idle. It should be ~14v. Turn on the
headlights, rear window defrogger, blower etc. You should hear the motor
drag down, and maybe the belt sing slightly. But you should still get
~14v, although you might need to give it another 1000 RPM.
Never ever disconnect the battery on a running car. It's a vital part of
the equation. If you disconnect it, you get what is called a "load dump"
-- the voltage shoots up to ~65V until, several hundred msec later, the
voltage regulator manages to get it down to reasonable levels again.
[The effective inductance of the alternator is ~~1H; that's why nothing
By that time, many of the exquisitely expensive electronic gadgets on board
may have let some of their magic smoke out....
As for jump-starting:
1) A battery being charged may vent hydrogen.
2) Hydrogen + sparks == kaboom.
It's the jumped battery that is getting rapidly charged after starting. So I
make it point to disconnect the first end at the jumping car. In a perfect
world, you could just use the block/frame for the ground connection, but lately
it seems like everything exposed under the hood is plastic or the wrong shape to
